inder throws outward the lower end of the lever 32, swinging said leveron its pivotal connection with the link 36 as a fulcrum and thussimultaneously drawing inward on the link that connects the upper end oflever 32 with the lever-arm 24,1 and drawing oppositely on the link 36that links said lever 32 with the lever 31, so that lever 31 and with itlink 29 and lever 23 are drawn inward at the same time that link 30 andlever 24 are drawn inward. This actuation of the floating lever 32 bythe piston rod 35, such lever 32 drawing simultaneously and oppositelyupon the link and link 36, obviously equalizes the pulls simultaneouslytransmitted to the lever-arms 23 and 2% respectively, so that saidlever-arms23 and 24: tend to be moved equally and simultaneously, inopening the doors, notwithstanding the fact that a variable strain maybe imposed on the opposite rock-shafts 21 by the possible differences inthe load resting upon the respective dump doors that are actuated fromsaid res ectively opposite rock-shafts.

When the opper has been cleared, the air pressure in the air-cylinder isreleased, and the dump doors swing back into their closed position,coming to a stop at such closed position by reason of the contact oftheir mutually meeting edges along the longitudinal median line of thedump opening and also by reason of the engagement of their upwardlyextended outer flanges 37' with the fixed downwardly extended flanges 38on either side of the dump opening of the hopper. Such swinging back ofthe dump doors into closed position is induced by their tendency togravitate from the upward position into which their opening movementshifts them, the pivot points of theirsupporting members being sopositionedas to facilitate this downward movement into closed position,and the said closing movement is consummated by the coiled springs 89secured to and coiled about the struts 40 that brace the dependingbrackets at either end of'the dump opening, the free ends of said coiledsprings being respectively secured at 41 to the respective rock-armsthat support the lower ends of the swinging arms upon which the dumpdoors are mountcd,-these springs being tensioned as the dump doors areforcibly opened, and such tension acting to impel the doors to closedposition when the power holding the doors open is released.

It is obvious that the mechanism above described provides an entirelysimple and positive method of motor control for the dump opening of ahopper car, and permits a s ngle car or a series or entire train of suchcars to be dumped simultaneously by ,a single application of the powertransmitted through the power or airline of such sefies or train.

My invention is herelnabove set forth as charge of said hopper andbodilymovable laterally outward; upwardly extending rock arms supporting thesaid doors from below; operating connections for opening said doors; anda power-operated motor for actuating the said operating connections toopen said doors'positively; substantially as specified.
